<p>A thermosetting composition which comprises (A) a polyhemiacetal ester resin having repeating units represented by general formula (1) (wherein R?1 and R2¿ each is a divalent organic group and Y is oxygen or sulfur) and (B) a compound having per molecule two or more reactive functional groups capable of forming a chemical bond with a carboxyl group and optionally further contains (C) an acid catalyst. It gives at a relatively low temperature a cured article excellent in chemical performance, physical performance, adhesion, smoothness, weatherability, etc., and has satisfactory storage stability. It is utilizable as the solvent-diluted type, solvent-free liquid type having an effective-ingredient content of 100 %, or powder type.</p> |
